Technical Abstract: We compared a simple and a complex, process-oriented ET model in terms of data requirements, ease of operation, and accuracy. Both models simulated daily and seasonal ET with reasonable accuracy. Advantages of the complex ET model included its ability to simulate hourly ET fluxes, individual plant species, and ET over a wide range of conditions without prior calibration. Disadvantages of the complex model were the large amount of input information required, the limited availability of such information for rangeland sites, and complexity of operation.
